All Flashcards
How do sequences prolong the tonic area?
By repeating patterns that emphasize notes within the tonic key, creating stability.
How do sequences signal motion to a new key?
By gradually introducing notes from the target key, often using chromatic alterations.
What is the function of a diatonic sequence?
To establish and reinforce the tonic key.
What is the function of a chromatic sequence?
To create tension, forward motion, and modulation.
How do diatonic sequences reinforce the tonic key?
By emphasizing notes within the tonic key, creating stability.
How do chromatic sequences create tension?
By introducing notes outside of the current key.
What is the typical function of a sequence moving by step?
Can prolong the tonic or modulate to closely related key.
What is the typical function of a sequence moving by third?
Can prolong the tonic or modulate to a more distant key.
What is the typical function of a sequence moving along the circle of fifths?
Often used for strong modulations to new keys.
What is a melodic sequence?
A musical idea (pattern) repeated at different pitch levels.
Define 'pattern' in a melodic sequence.
The original musical idea that is repeated.
What is 'level of transposition'?
The interval by which each repetition of the pattern is shifted.
What is a diatonic sequence?
A sequence that stays within the key; interval quality may change.
What is a chromatic sequence?
A sequence that uses accidentals to maintain exact interval quality.
What is an ascending sequence?
A sequence where the pattern moves upward in pitch.
What is a descending sequence?
A sequence where the pattern moves downward in pitch.
What does it mean to prolong the tonic area?
Repeating patterns that emphasize notes within the tonic key to create stability.
How do sequences signal modulation?
By gradually introducing notes from the target key.
What is the function of melodic sequences?
Prolonging the tonic area or signaling motion to a new key (modulation).
